1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

introductionUp to one-third of women of reproductive age experience heavy menstrual bleeding (HMB). HMB can give rise to iron deficiency (ID) and, in severe cases, iron-deficiency anemia (IDA).

aimTo review current guidelines for the management of HMB, with regards to screening for anemia, measuring iron levels, and treating ID/IDA with iron replacement therapy and non-iron-based treatments.

methodsThe literature was searched for English-language guidelines relating to HMB published between 2010 and 2020, using the PubMed database, web searching, and retrieval of clinical guidelines from professional societies.

resultsOverall, 55 guidelines mostly originating from North America and Europe were identified and screened. Twenty-two were included in this review, with the majority (16/22) focusing on guidance to screen women with HMB for anemia. The guidance varied with respect to identifying symptoms, the criteria for testing, and diagnostic hemoglobin levels for ID/IDA. There was inconsistency concerning screening for ID, with 11/22 guidelines providing no recommendations for measurement of iron levels and four contrasting guidelines explicitly advising against initial assessment of iron levels. In terms of treatment, 8/22 guidelines provided guidance on iron therapy, with oral iron administration generally recommended as first-line treatment for ID and/or IDA. Four guidelines recommended intravenous iron administration for severe anemia, in non-responders, or before surgery. Three guidelines provided hemoglobin thresholds for choosing between oral or intravenous iron treatment. Four guidelines discussed the use of transfusion for severe IDA.

conclusionMany of the guidelines for managing HMB recognize the importance of treating anemia, but there is a lack of consensus in relation to screening for ID and use of iron therapy. Consequently, ID/IDA associated with HMB is likely to be underdiagnosed and undertreated. A consensus guidance, covering all aspects of screening and management of ID/IDA in women with HMB, is needed to optimize health outcomes in these patients.
